... I am utterly and completely lost.

http://drupal.org/node/58633 is a patch to change theme('add_style') into theme_add_style.

Is theme _add_style the ont theme function that is not a theme function? Or is this just coded VERY incosistent.

And what about theme(stylesheet_import) should that too be theme_stylesheet_import, or is tata one correct, and called via theme() ?

I would love some clarification. This needs

* documentation * a bug/task to solve right away (as in: after the release)

Which I can open/create, provided I have a clear understanding of the problem.

The fact that there is so much confusion, BTW, points out that, eventhough there might be no bug, or problem technically, there still is a lot of room for improving this strange thing.
